Be it known that I, Jol-LN C. Ross, a citizen of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented certainr new and useful Tmprovements in Dispensing atpparatus, of which the following isa specification.

This invention relatesto an improved, lubricant dispensing apparatus and has as one of its principal objects to provide a device for discharging. both lubricating oil and hard grease.

A still further object of the invention in this connection is to provide an apparatus wherein, when desired, a continuous dis-v charge flow of lubricating` oil may be had.

rind the invention has asa still further object to provide an apparatus which, in being capable of dispensing either hard grease or lubricating oil, will be particularly adapted for use in lubricating the journals of mine car wheels or in other situations where the use of both hard grease and fluid lubricant isfound necessary.

Other and incidental objects will appear hereinafter.

In the drawings: j

Figure 1 is a fragmentary perspective view of my improved apparatus.

Figure 2 is a fragmentary elevation yofthein section.

Figure 8 is a` vertical sectional view taken at substantially right angles to Figures 2.

Figure 4 is a fragmentary section showing the circuit breaker employed in connection with the air pump of the device.

Figure 5 is a detail sectional View oi.t the intake and discharge .fitting employed in.y connection with thi.` lubricating oil container of the device.

lu carrying the invention into effect, 'Il cniploy a cylinder 10 which -provides a hard grease container. This cylinder is supported in vertical position by a suitable stand and mounted upon the upper end of said cylinder is a pump casing 11 normally closed by a door 12. Upstanding from the pump casing in axial aliiiemeiit with the cylinder 10 is an air cylinder 13 and reciprocable in this cylinder is a piston 14 having a piston rod 15 extending through the pump casing and carrying at its lower end a piston 16 reciprocable within the cylindei` 10. Arranged within the pump casing is an air pump 17 1920. semaine. 400,027.

mounted to oscillate upon a yoke 18 and, as will be observed upon reference to Figure 2 of the drawings, the pump piston is connected to a gear wheel 19 preferably driven by an electricinotor 2O of suitable type. Thus, when the gear wheel 19 is turned by the motor 20, the pump piston will be reciprocated. Communicating `through the yoke 18 with the pump cylinder is a pipe 21 connected to a pipe 22 entering opposite'ends ofthe cylinder laiid interposed in this latter` pipe are three way valves 23. To the stems of said valves are connected levers 211, the lowermost of which is elongated to provide a handle and coupling said levers to rock in unison is a. connectii'ig rod 25. This redis, as shown in detail in Figure 9, formed of pivotally connected sections, the uppermost of which is channeled to receivethe adjacent end portion of tlielower section of the rod frictionally coacting therewith for holding the rod sections in alinemeiit, and .is provided with a laterally projecting thumb lug 2G. As will be clear, this lug may be grasped for swinging `the meeting ends of the rod sections laterally outward and .thusbreak y nig the rod. Associated with the motor 2O is a circuit breaker shown in detail in Figure i of the drawings. This circuit breaker includes a casing 27 which is in communication with the pipe 22 througha pipe37` and is supported by a bracket 28 secured to the ycasing 11. Pivoted upon the casing 2.7 is

an arm 29 extending downwardly in front of the outer end of said casing and slidable within the :rising is a piston 30 having a pistou rod 31 extending freely through the outer end wall of the casing to confront the free end of the arm 29. The piston rod is equipped wi th a shoulder 32 for limiting the pistony in its inward movement and bearing between the piston and the outer end of the casing is a helical spring 33 surrounding the piston rod and normally acting to hold the piston retracted. Beneath the free end of the arm 29 is mounted upon the pump casing a bracket 34 insulated from the casing and forming a iixed switch contact. Upon` said bracket is pivoted a movable switch contact 35 insulated from the fixed contact and adapted to coact therewith at its lower end while the upper end ofthe movable contact extends in front of the lower end of the ai'ni 29. Projecting from the bracket 34 is an arm 36 and rextending between this arm and the lower end portion of the contact is a spring 37 normally holding the switch closed.

A feed wire is connected to the movable contact 35 and another wire lis connected to the fixed contact to lead to the motor. Thus, current will normally be supplied through the switch to the motor 2G. However, as soon as the air pressure in the pipe 22 becomes sucient to overcome the spring 33 of the circuit brealrenthe'piston 30 will be moved outwardly whenthe piston rod 31 will press `the free end of the arm 29 against the upper end portion of the pivoted contact 35 of the switch. rlhe switch will thus be opened and will be held open vuntil the pressure in the cylinder falls when the spring 33 will retract the piston so that the pivo-ted contact 35 of the switch will lbe freed and again closed by the spring 37. When this occurs, the motor will, of course', be again started.

Leading from the lower end portion of the cylinder 10 is a discharge pipe 38 in which is preferably interposed a valve 39 andconnected to said pipe is a discharge hose 40. Thus, asv will now be readily understood in view of the preceding description, the valve levers 24 may be swung upwardly for admitting air to the cylinder 13 above the piston 14 and relieving t-he cylinder below the piston, when this piston will be driven downwardly within the cylinder to, in turn, depress the piston 16 -for discharging grease through the .hose 40 from the cylinder 10. On the other hand, by swinging the kvalve levers downwardly, the piston 16 'may be elevated when a further supply of grease may be introduced into the greasev cylinder, it being observed in this connection that when the piston 16 is4 at the top of its'4 stroke, grease may be introduced into the cylinder 10 through theV door opening of thepump casing A11.v

Extending from the pipe 2l is a pipe 4l in whichis interposed a valve-42 and connected to said pipe is a hose 43. The hose is ot' a length to extend to a suitably located lubricating oil.- container 44.A Extending downwardly into this container, as particularly shown in Figure 5, isa pipe upon the upper end of which is threaded a T-coupling 46. The hose 43 is, as will be noted, connected to this coupling and? threaded through 4the upper end of the coupling is a lubricant discharge pipe 47 of a diameter somewhat less than the pipe 45 and extendingdownwardly within said pipe into the container. 'Io the upper end of the pipe 47 is connected a discharge hose 4S. 'As will be clear, the valve 42 maybe opened y'for admittingair through the hose 43 into the container 44. Air pressure in the container will then serve to expel the lubricating oil within the container through the pipe 47 and hose 4S.

Having thus described the invention, what is claimed as new is:

l.'In a dispensing. apparatus, the combination of alined cylinders, a. casing coni necting said cylinders, pistons in said cylinders coupled with each other, one of thel cylinders opening into the casing whereby such cylinder may be filled through the casing, and means normally closing the casing. Y

2. In a dispensing apparatus, the combination of alined air andsupply cylinders, a casing connecting said cylinders, pistons in said cylinders coupled with each other, the supply cylinder opening into the casing whereby such cylinder may be iilled through the casing, a pump in said casing for supplying air to the air cylinder, and means normally closing the casing.

In testimony whereof I aliix my signature.
